Title: Improvements in or relating to methods of and apparatuses for SZ stranding individual strands or strands combined into twisted or non-twisted bundles
IPC: H01B13/04
Filed: 1979-01-03
Abstract: A communication cable is formed by SZ stranding individual strands or twisted or untwisted bundles of strands. The strands move at a constant speed through a front stranding nipple 2, ring 4 and stranding nipple 6 which continuously and periodically reciprocate in the direction of movement of the strands at a constant speed less than that of the strands, and a fixed, continuously rotating stranding head 9. A second stranding head 7 is disposed directly behind nipple 5 and rotates in the same direction as the fixed stranding head 9. The second stranding head 9 reciprocates with nipple 5. <IMAGE>

Title: Method at the making of bodies of granular and/or fibrous material with sodium silicate or potassium silicate as binder
IPC: B22C1/18
Filed: 1979-03-07
Abstract: Certain disadvantages of using sodium or potassium silicate as binder for granular and/or fibrous material can be overcome by adding a surface-active substance to the moulding material. The additions furthermore make it possible to reduce the amount of added alkali silicate compared with the amount heretofore usually added, without decreasing the strength of the mould or core when this constitutes the body formed from the moulding material. The surface active substance may be a surfactant or silicone.

Title: Chemical pickling stainless steel
IPC: C23G1/08
Filed: 1979-04-04
Abstract: The scale on the surface of a stainless steel article is removed by dipping in an aqueous solution containing nitric acid, hydrofluoric acid and from 0.05% by weight to 5% by weight of urea. The amount of the urea in the aqueous solution is advantageously adjusted so as to be present in a mol ratio to nitrous acid generated during the dipping, of less than 1. The effectiveness of the scale removal is increased if the scale on the articles is mechanically broken before dipping. Preferably the articles are dipped in a sulphuric acid solution before being dipped in the nitric acid - hydrofluoric acid solution containing urea. The dipping in the acid solutions may be repeated to produce particularly good results.

Title: Adaptive equalizer
IPC: H03H21/00
Filed: 1979-04-12
Abstract: An automatic adaptive equalizer operates on a test pattern including a carrier-only period, a clock-only period and a single test impulse. The equalizer employs a transversal a filter under control of a microprocessor 23. Samples Xi and Yi of in- phase and quadrature phase components of the received impulse response are cross-correlated and auto-correlated to form elements of a complex matrix equation describing the optimum equalizer tap settings Cp1 and Cq1 etc. The microprocessor performs a special iterative operation utilizing elements of this equation to rapidly and exactly calculate the optimum initial settings for the tap constants. The clock- only portion of the test pattern is analyzed to set a sampling clock to sample the received impulse so that the tap constant calculation can be carried out within the duration of the received impulse. Initial equalization can be achieved in a time of about 30 milliseconds at a data rate of 9600 bits per second. <IMAGE>
